According the different thermocoupe wire,thermocouple has four type are S,R,Band WRe Type.
| Type | Model | +leg | -leg |
| R | QR-KR | PtRh13% | Pt |
| S | QR-KS | PtRh10% | Pt |
| B | QR-KB | PtRh30% | PtRh6% |
| WRe | QR-KW | WRe3% | WRe25% |
| Type | Model | Max.working Temperature°c | Wire diameter(mm) |
| R | QR-KR | 1760°c | 0.04 |
| S | QR-KS | 1760°c | 0.04 |
| B | QR-KB | 1800°c | 0.04 |
| WRe | QR-KW | 1820°c | 0.1 |
Accroding the different thermocouple connector,thermocouple head can be divide in 602 type and 604 type.
| Type | Model |
| 602(Round bottom) | QR-KR/S/B/W-602 |
| 604(Triangle bottom) | QR-KR/S/B/W-604 |
Accroding the different thermocouple wire tolerance,It have two type are common thermocouple wire(P) and exact thermocouple wire(J).
| Type | Model | Accuracy |
| P(common wire) | QR-KR/S/B/W-604/602P | ≤5°c |
| J (exact wire) | QR-KR/S/B/W-604/602J | ≤2°c |
